Exercise intensity, exercise training and energy metabolism in overweight and obese males

Roffey, Darren M. (2008) Exercise intensity, exercise training and energy metabolism in overweight and obese males. PhD thesis, Queensland University of Technology.


The primary objective of this PhD program was to investigate the impact of training at a constant-load moderate-intensity (FATmax) compared to work-matched high-intensity intervals (HIIT) on the metabolic, physiological and psychosocial health profiles of sedentary overweight and obese men. This study was unique in that it was the first time the effect of exercise intensity had been investigated to examine concurrently the components of whole-body energy metabolism and body composition as measured using gold standard techniques.

Based upon the positive alterations in blood lipids, body composition, cardiorespiratory fitness and substrate oxidation, it appears that training at FATmax can positively impact health parameters as well as, or if not better than, high-intensity training. Furthermore, there are ramifications for public health messages and obesity management strategies arising from these findings, primarily attributable to the increased exercise adherence and the reduction in health risks stemming from the significant loss of abdominal visceral adipose tissue after FATmax training.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
